One of the best tech events of this past spring was hosted by Nathan Kaiser, CEO of nPost.com. Nathan has put together a follow-up event (more to come later this summer and fall), with a new batch of local startups that will be on hand to demo their products. The list includes Catch the Best, Eyejot, Timelope, HomeSavvi and ClayValet, plus one or two others. It looks like there’s still room on the registration page to sign up – the event is free, and if the last one was any indication, it should be a blast!

Mashable, the social network blog, is doing a little bit of networking of its own this summer with a party tour around the country. And, because Seattle is the hotbed of innovative tech right now, they’re kicking things off right here, in our very own backyard. This Saturday night, the company is hosting a big event at the Showbox SoDo with food, drinks, music, all the usuals! They’ve been promoting this pretty heavily on the startup scene around here, so you can expect a good showing by some of the local luminaries. Festivities kick of at 7pm – buy your tickets now, before they sell out.

When it comes to cool tech events here in Seattle, the East Side always seems to draw the short straw. Which is why when a really cool event (like a Jane and Robot meetup) rolls around, we want to draw as much attention as possible. Vanessa Fox and Ignition Partners are hosting a get-together to talk about website design from both a usability standpoint, as well as search engine optimization standpoint. Jeff Pollard of SEOmoz.org will be on hand to add his expertise to the discussion. Make sure you register on the upcoming page, and then head over to Bellevue tonight!

Amidst all the tech parties, happy hours and startup competetions, you might just be looking to hang out and drink and talk about science for an hour or so. Well, lucky for you, the Science on Tap events at Ravenna Third Place Books are still going strong through the summer. This month, science writer Sally James is going to be talking about science is represented and reported in the mainstream media. As always, no science expertise is required, just swing by, have a pint and enjoy the chat.

As we’ve mentioned before, the Seattle startup industry is still booming with at least one new event every week. This Friday afternoon, up-and-coming entrepreneurs will get the opportunity to hone their idea-pitching skills. FundingUniverse.com will be giving about 15 local early stage founders 2 minutes to pitch their idea before a panel of experts (representatives from Atlas Recruiting, nPost.com, ActiveWords and others). They’ll be judged by the panel and also getting feedback from the larger audience. Check out the FundingUniverse.com event page for more details.

Submissions for the competetion itself are already closed, but you can still sign up to attend. If you plan on going, make sure you either RSVP over at the upcoming.org registration page, or send an email directly to Carolynn Duncan: cduncan@fundinguniverse.com. They only have room for 130 people and are already over half full, so make sure you register soon.

As we mentioned last week, this is the weekend for tech events, and tonight the events kick off with a whole bunch of drinking. At 4:30, Josh Maher is organizing a Lunch 2.0 Happy Hour event at the offices of Blue Gecko downtown. From there, at 6pm, Nathan Kaiser and the other nPost.com pub crawlers will be heading out to a couple of bars before Thingamajiggr kicks off at 8pm. You can either show up at the Blue Gecko event, or follow along with the nPost twitter feed to see where folks are. The nPost wiki also has the evening’s rough schedule sketched out, so you can check for updates there as well.
